p = 0.318 (between blood lactate and PRISM III)

p = 0.135 (between blood lactate combined with PRISM III and PRISM III alone)

p = 0.018 (between blood lactate combined with PRISM III and blood lactate alone)

  1. AUC, area under the receiver-operating-characteristic curve; CI, confidence interval; PRISM III, pediatric risk of mortality III.
